SPIKE-FULLER.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed August 7, 1916. Serial No. 113,520.

To all whom it may concern:

Be it known that T, Janus F. CRAVEN, a resident of Pittsburgh, inthe county of Allegheny and State of- Pennsylvania, haye invented a new and useful Improvement in Spike-Pullers, of which the following is a specification.

This invention relates to spike pullers and the object is to provide a tool adapted to draw various kinds of spikes, nails, etc., from material into which they have been driven. More particularly it is intended to provide a tool for pulling spikes from railroad ties and especially cooperating locked spikes which have been driven in pairs.

In a pending application, Serial No. 59395, filed Nov. 3, 1915, and inanother application, Serial No. 113,519, filed of even date herewith, I have described spikes designed to be driven into railroad ties in pairs, one being driven vertically, and the other by the side of the first but at an angle thereto; the two heads in final position being side by side and corresponding in shape to the ordinary single spike head. These spikes are made with their heads extending laterally from one side of the shank, but on the other side the head having a face flush with the side of the shank. These fiat sides fit together so that the two spikes may lie in contact when driven side by side, Thus there results a rounded head, parted in the middle and having an extended flange on each side on separate spikes, as shown in the drawings and described in said pending applications. These spikes cannot be readily drawn with the ordinary tool, as their diverged points and interlocked relation prevent the two being drawn simultaneously; and it is hard to engage the head on one with a tool or claw lever without engaging both. The present invention is particularly designed to meet this condition, though it may be used for other purposes, as will be ap arent.

ne embodiment of my invention is shown in the drawings, wherein Figure 1 is an elevation of my device as applied to a pair of special railroad tie spikes; Fig. 2 is a partial elevation of the device applied to an ordinary spike; Fig. 3 shows details of the end of the tool adapted to pull the first of a pair of locking spikes; Fig. 1 shows details of the other end, adapted to pull the remaining vertically driven spikes; and Fig. 5 shows the head arrangement of the driven of its sides 4 and its rear wall 5, while the other wall 6 is perpendicular. This notch is adapted to engage the perpendicularly driven spike S. The inner plane face of the head H of that spike fitting against the wall 6 of the claw, and the outer flange F of the head being engaged by the beveled face 4. Thus this claw end will slip under the head of the perpendicular spike and pull it, in the usual manner of such tools as is well understood.

The other end of the lever is enlarged and bent to form a rounded head 7, having a terminal recess 8, bounded by beveled walls 9 and 10, corresponding to beveled walls t and 5, above described, but oppositely disposed. A bolt or rivet 11 passes through the head 7 and forms a bearing for a cooperating member 12, carried by the bolt. This member 12 has a base 13, adapted to seat on the medium into which the spikes are driven, and to form a fulcrum for the tool, as later described. The other end of the member 12 forms an extension 14, having its under face concave to fit over the rounded head of spike S.

WVhen it is desired to pull the two 00- operating locked spikes, the tool is first used as shown in Fig. 1, 2'. e., the jaw 7 is advanced under the head of the inclined spike S, the beveled faces 9 and 10 engaging the inclined outer flange F as will be obvious. The jaw or extension 14 passes over and seats on top of the head H of the vertically driven spike S. When downward force is applied to the free end of the lever, it is fulcrumed on the pin 11, so that pressure of extension 14: is downward on the spike S, holding it in position while the jaw 7 raises the other spike S. Toward the end of the movement, the rounded .side of the head 7 seats on the base 13, and then the fulcrum shifts to the rear edge of that base, and aids in the quick removal of the spike. The head H of spike S cannot slip out of engagement with the beveled faces 9 and 10, as the other and plane side of the head lies against the vertical spike S.

After pulling the inclined spike S as above described, the tool is reversed, and the other end having the notch 3 is applied to the vertical spike S. The beveled walls a and 5 engage the outer flange of the head H and the vertical Wall fits against the inner face of the head which is flush with the shank of the spike, securely gripping it, as will be obvious.

By this tool the pairs of locking spikes of my other inventions are readily drawn, without greater difliculty than with any two spikes.

The many advantages of my invention will be apparent to those familiar with the art.

I claim 1. A tool for pulling spikes driven in pairs, comprising a lever having a jaw adapted to pass under one spike head and a pivotally attached jaw adapted to be seated upon the other spike head and to form the fulcrum of said lever.

2. A tool for pulling spikes driven in Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

pairs, comprising a lever arm having a claw head adapted to engage one spike, and a member carried by the claw head adapted to seat on the other spike and to form the fulcrum for said lever.

3. A tool for pulling spikes driven in pairs, comprising a lever arm having a claw head having a beveled recess to engage the head of one of the spikes, and a member carried by the claw head adapted to seat on the other spike and to form the fulcrum for said lever.

4. A tool for pulling spikes driven in pairs, comprising a lever arm having a claw head adapted to engage one spike, and amember pivotally carried by the chm head having an extension with an under face adapted to seat on the other spike and a base adapted to form the fulcrum of the lever.

In testimony whereof, I have hereunto set my hand. JAMES F. CRAVEN l/Vitnesses: I
